Computer hardware consists of technology for computer processing, data storage, input, and output, such as large mainframes, servers, midrange computers, desktop and laptop computers, and mobile devices. Computer software includes both system software and application software. System software, such as the Windows operating system, manages the resources and activities of the computer.

Data management technology is specialized software to organize the data and make it available to business users. Networking and telecommunications technology provides data, voice, and video connectivity to employees, customers, and suppliers. Technology services includes the people to run and manage the other infrastructure components and to train employees in how to use these technologies for their work.
